Typical Applications (Page 1 of 4)
The following example illustrations show typical applications of various highway work zones. These examples cover a variety of situations commonly encountered in work zones.
In general, these illustrations show minimum solutions. The information can be adapted to a broad range of conditions.
These illustrations do not address the use of law enforcement officers in work zones. Additionally, officers should use judgment based on the traffic control setup, site characteristics, and location of adjacent driveways or parking lots.
They are intended as a guide to help you identify possible inappropriate and unsafe traffic control setups and conditions.
You must study the roles of law enforcement officers in work zones carefully on a case-by-case basis. State and local standards, guidelines and regulations may vary.
